openvdb::OPENVDB_VERSION_NAME::compression::Page Class Reference

Stores a variable-size, compressed, delayed-load Page of data that is loaded into memory when accessed. Access to the Page is thread-safe as loading and decompressing the data is protected by a mutex. More...

Member Function Documentation

const char* openvdb::OPENVDB_VERSION_NAME::compression::Page::buffer

(

const int

index

)

const

Retrieves a data pointer at the specific.

Parameters

index

Note

Will force a Page load when called.

bool openvdb::OPENVDB_VERSION_NAME::compression::Page::isOutOfCore

(

)

const

Test if the data is out-of-core.

void openvdb::OPENVDB_VERSION_NAME::compression::Page::load

(

)

const

load the Page into memory

void openvdb::OPENVDB_VERSION_NAME::compression::Page::readBuffers	(	std::istream &	,

	)

Read the Page buffers. If delayed is true, stream pointers will be stored to load the data lazily.

void openvdb::OPENVDB_VERSION_NAME::compression::Page::readHeader

(

std::istream &

)

Read the Page header.

long openvdb::OPENVDB_VERSION_NAME::compression::Page::uncompressedBytes

(

)

const

Uncompressed bytes of the Paged data, available when the header has been read.
